### 1/5 — Several tweaks needed

*2025-11-10*

This app should work to sync data amongst my iPad my phone and my watch but doesn’t. I have to choose which one to work with and be near it to enter data. The ability to edit water after the fact because this doesn’t sync amongst the three devices adds to the annoyance. And sometimes the water “meter” does not rest to zero for new day or fasting period. Overall nice app but not worth the money I paid. I’d go freebie version instead. Finally, while I can edit windows, I’m noticing that accuracy is not consistent - reports streaks that are actually far longer than posted … that I find particularly irritating! I have to go in and edit or just accept it believes that I broke I fasting streak when I didn’t. 
Lagging and odd delays with from one screen to another getting excessive and frustrating!

**Developer response:** Hi Paulla Kay! Thank you for reaching out. We appreciate if you could contact our support service (support@window-fasting.com) with a more detailed description of the issue so that we could try to resolve it for you. Thank you in advance for your cooperation! We're willing to help.

### 1/5 — Manual says free but won’t work.

*2025-11-06, version 4.3.11*

It says the manual plan is free but it won’t work. I emailed them and they claimed had to by my phone and that I needed to reset it. I did everything I could on my end but nothing works. It’s an issue with the app.

### 1/5 — ไม่ดี

*2025-11-02, version 4.3.11*

ตัดตังฉันไปจ้าไม่คืนด้วย

### 4/5 — Liked the app

*2025-10-16, version 4.3.11*

I like the app, I’ve had it for 2.5 years.  For the last year, it seems that it takes forever to record my data and there should t be a problem as I have a smartphone and tons of available GB space.  I’m assuming that since I bought the app and now whoever owns the app wants me to buy a new version which I don’t need!!??

### 1/5 — STEALING MY MONEY

*2025-10-12, version 4.3.11*

I did a free trial for this app previously called Fasting by Apalon LLC. The app was deleted and it wasn’t a right match. They now charge me a YEARLY subscription that I cannot cancel because the app is no longer by the same company. Now it is owned by Thriveport. I have no way to cancel because my subscription cannot be found because the app has changed hands, although I have receipts of this app withdrawing $39.99 from my account every year!!! I never get response when emailing and I am TIRED OF IT!!!

### 1/5 — Business sketchy practices

*2025-07-03, version 4.3.11*

I purchased this app years ago, well before subscriptions existed. You’d think the company would appreciate long time customers. Not in the slightest. The app keeps telling me to restore my purchase but when I click the button nothing happens. I’ve emailed the support and I’ve gotten no response.

### 1/5 — Manual Plan is not working

*2025-06-19, version 4.3.11*

manual plan, 到現在還是不能用

### 5/5 — ใช้งานได้ดีค่ะ เเต่เจอว่ามีบัคบางส่วนนะคะ

*2025-06-19, version 4.3.11*

ในส่วนของ ประวัติ รายวัน รายสัปดาห์ รายเดือนเเสดงข้อมูลไม่ตรง

### 3/5 — Plano Manual não funciona mais

*2025-04-06*

Depois de uma atualização uns meses atrás o Plano Manual parou de funcionar, ao clicar nos botões disponíveis nada acontece.

### 1/5 — Não funciona

*2025-03-30*

O app não está funciona no modo manual. Você só consegue se pagar.
